QRISK2 10-Year Cardiovascular Risk Estimator
Use this quick tool to estimate 10-year risk of heart attack or stroke. This is an educational approximation and not a clinical diagnosis.
What is QRISK2?
QRISK2 is a cardiovascular risk model used in UK primary care to estimate the chance of having a heart attack or stroke over the next 10 years. It combines common risk factors—such as age, blood pressure, cholesterol ratio, smoking, and long-term health conditions—into a single percentage estimate.
In clinical practice, QRISK tools help doctors and patients make shared decisions about prevention, including lifestyle changes and, in some cases, medication like statins or blood pressure treatment.
How to use this calculator
Step-by-step
- Enter your age, sex, and ethnicity.
- Select your smoking status.
- Add systolic blood pressure, cholesterol/HDL ratio, and BMI.
- Tick any medical conditions that apply.
- Choose your diabetes status and deprivation quintile.
- Click Calculate Risk.
The result includes an estimated 10-year percentage risk, an approximate risk category, and an estimated “heart age” to help communicate long-term impact.
Interpreting your result
Risk bands (general guide)
- Low: under 5%
- Borderline: 5% to 9.9%
- Higher risk: 10% or more
In many UK pathways, a 10-year risk of 10% or higher may trigger discussion of preventive treatment alongside lifestyle improvement. Your own target and treatment plan should always be personalized.
Why risk calculators matter
Most cardiovascular events are not caused by one factor alone. Instead, risk accumulates across blood pressure, lipids, inflammation, diabetes, smoking, and social determinants. A structured calculator helps prioritize prevention before symptoms appear.
- Supports earlier intervention
- Improves risk communication in clinic
- Tracks risk over time as habits and treatment change
- Helps identify people who might benefit most from therapy
Ways to lower your 10-year cardiovascular risk
Lifestyle fundamentals
- Stop smoking and avoid secondhand smoke exposure.
- Increase activity: aim for at least 150 minutes/week moderate exercise.
- Improve diet quality: more vegetables, legumes, fiber, and unsaturated fats.
- Reduce excess weight gradually if overweight.
- Limit alcohol and protect sleep quality.
Medical optimization
- Control blood pressure with monitoring and treatment adherence.
- Manage diabetes tightly and review HbA1c regularly.
- Address lipid profile with lifestyle and medication when appropriate.
- Review kidney and heart rhythm conditions with your clinician.
Important limitations
This web tool is designed for educational use and is not a replacement for official clinical software. A full clinical QRISK workflow uses complete health record data, validated coefficients, and careful interpretation by a healthcare professional.
- Not for emergency symptoms (chest pain, stroke signs, collapse).
- Not intended for people outside standard age range.
- Cannot account for every relevant condition or medication.
- Should not be used as your sole basis for treatment decisions.
Final takeaway
A QRISK2-style estimate is most useful when it starts a conversation: what your current risk looks like, what can be changed, and which actions give the greatest benefit over the next decade. If your result is elevated, book a preventive cardiovascular review and create a realistic plan.
